I will rephrase. The BIP reads:

lead to undesirable failure modes in applications whose safety
critically relies on responding to certain
on-chain events.
I understand that the compact header chain is used to mitigate against
this, but I am unsure about the use
cases and trade-offs.
For a normal wallet, the only thing I can imagine an attacker could do
is pretending a transaction did not confirm
yet, causing nuisance.
An application critically depending on knowing what happens on-chain
surely is better off downloading
the TXIDs, providing PoW security? Gaining knowledge of incoming TXIDs
is nicely solved the payment protocol.
Are there enough use cases that critically depend on pub key hashes
being used on-chain, to make the compact header chain worth its costs?
Regards,
Tomas
